/ˌɡ(j)ubərˈnækjələm/

Inflections: Plural gubernacula.

Origin: A borrowing from Latin. Etymon: Latin gubernāculum.

Etymology: < classical Latin gubernāculum steering oar of a ship, in post-classical Latin also each of the hind legs of a locust (1524 in a translation of Aristotle, after ancient Greek πηδάλιον , used in both senses) < gubernāre govern v. + -culum -culum suffix.In gubernaculum dentis at sense 2b < scientific Latin gubernaculum dentis (1817 or earlier) < classical Latin gubernāculum + dentis , genitive singular of dēns tooth (see dental adj.).

†1. In plural. The hind legs of a locust, esp. when involved in stridulation. Obsolete. rare.

b. More fully gubernaculum dentis. A cord or sheath of connective tissue that connects the sac of an unerupted permanent tooth with the surface of the gum.

gubernaculum testis n. [ < scientific Latin gubernaculum testis (1762: see quot. 1762) < classical Latin gubernāculum + testis , genitive singular of testis testis n.²] Embryology a cord of connective tissue which connects the testis and the scrotum in a male fetus, and is involved in the descent of the testis into the scrotum.

ΚΠ

1762 J. Hunter in W. Hunter Med. Comm. ix. 78 It turns inwards from the lower end of the epididymis, under the lower end of the testis, and behind the upper end of a ligament or gubernaculum testis, which I shall presently describe.

1903 J. B. Deaver Surg. Anat. III. 90 The upper one of these [folds of peritoneum] ultimately contains the spermatic vessels, and the lower transmits the gubernaculum testis.

2007 H. Schatten & G. Constantinescu Compar. Reprod. Biol. ii. 9/2 The remnant of the gubernaculum testis following the normal positioning of the testicle is a structure divided in three parts: the proper ligament of the testicle, the ligament of the tail of the epididymis, and the scrotal ligament.
